sp. nov. and sp. nov., novel bacteria isolated from bark of birch tree () No Access

Abstract

Two reddish-coloured bacterial strains (HMF7604 and HMF7620) were isolated from bark of birch tree () together with two strains (designed as HMF7603 and HMF7618). Cells were observed to be Gram-stain-negative, oval- to short rod-shaped and non-motile. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the four isolates belonged to the genus , family . They had the highest similarities (95.4–95.6 %) to ID1504, with which they formed a clade in phylogenetic trees. Menaquinone-8 was the only respiratory quinone. The predominant fatty acids were summed feature 3 (C 7 and/or C 6), C 6, C and C. Strain HMF7604 contained two unidentified phosphoglycolipids, nine unidentified glycolipids, one unidentified aminolipid, three unidentified phospholipids and three unidentified polar lipids, while strain HMF7620 contained one unidentified phosphoglycolipid, four unidentified glycolipids, one unidentified aminophospholipid, one unidentified phospholipid and one unidentified polar lipid. The DNA G+C contents of strains HMF7604 and HMF7620 were 65.6 and 65.7 mol%, respectively. The average nucleotide identity and digital DNA–DNA hybridization values between the two isolates and their close relative were 81.1–95.3 and 24.5–61.6 %, respectively. Based on the results of phenotypic and phylogenetic characterizations, the four isolates are considered to represent two novel species of the genus , for which the names sp. nov. and sp. nov. are proposed. The type strains are HMF7604 (=KCTC 43354=NBRC 115489) and HMF7620 (=KCTC 43051=NBRC 113959).
